Version 2.5.0

• Support for click callbacks for the table renderer, resolving the oldest open issue #33 (see example at http://nicolas.kruchten.com/pivottable/examples/mps_prepop.html)
• Support for sorters-aware <, >, <= and >= prefixes in the filter menu search box, as well as ~ for regex
• UX improvements to the filter menu: the UI doesn't refresh if no changes are made, and the Cancel button undoes any changes that were made
